German police have arrested a Lebanese national on suspicion of being a member of Hamas and planning attacks in Europe. The man, named as "Mohammad S", was stopped at Berlin's Brandenburg Airport after arriving from Beirut on Friday evening. Federal prosecutors said that in August 2025 he helped procure 300 rounds of ammunition and was involved in an alleged plot to attack Jewish and Israeli institutions. He is due to be brought before a federal judge who will decide on a pretrial detention.
